Abstract

Method of producing an oblong shell member made of fiber composite material by means of vacuum infusion, where the fiber material is impregnated with liquid polymer. A mould is applied with a mould cavity, in which a fiber insertion (3) with a first lateral face (1) and a second lateral face (2) is placed, and where said fiber insertion includes a plurality of fiber layers and a distribution layer (4), said distribution layer allowing a higher rate of flow for the liquid polymer than the fiber layers. A semi-permeable membrane (5) is placed opposite the first lateral face (1) of the fiber insertion, said semi-permeable membrane being substantially permeable to gasses and substantially impermeable to liquid polymer and further communicating with a vacuum source The distribution layer (4) is placed inside the fiber insertion (3) with fiber layers on both sides and is interrupted by a zone (6) opposite the semi-permeable membrane (5) Liquid polymer is directed via inlet channels (7, 8) to the distribution layer (4), thus creating a flow front (9, 10) between the distribution layer (4) and the second lateral face (2), said flow front moving through the central zone (6) towards the semi-permeable membrane (5)
